Changing the default system font on Windows 10 requires modifying the Windows Registry. Here are the steps to follow:

  1. Open the Registry Editor by pressing the Windows key + R, typing “regedit”, and hitting Enter.
  2. In the Registry Editor, navigate to the following location:

    HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\FontSubstitutes

  3. Right-click on an empty area in the right pane and select “New” > “String Value”.
  4. Name the new string value “MS Shell Dlg” (without the quotes).
  5. Double-click on the “MS Shell Dlg” string value and enter the name of the font you want to use as the default system font. For example, “Segoe UI” or “Arial”.
  6. Click “OK” to save the changes.
  7. Repeat steps 3-6 for the “MS Shell Dlg 2” string value.
  8. Close the Registry Editor and restart your computer for the changes to take effect.

Note: Modifying the Windows Registry can cause problems if done incorrectly. Be sure to create a backup of the registry before making any changes, and follow these steps carefully.
